(2009)A purified stem bark extract from Schizanthus grahamii was analyzed by combining capillary gas chromatography with a selective nitrogen phosphorus detector, mass spectrometry and Fourier transform infrared spectroscopy. ...
-
(2009)In the process of evaluating intrinsic electronic chemical potentials and related properties of anions in the gas phase, positive values for this quantity often arise. We herein examine in detail this result in terms of ...
-
(2009)The dispersion relation for circularly polarized electromagnetic waves propagating in the direction of an external magnetic field in a relativistic electron-positron plasma with arbitrary constant drift velocities is ...
-
(Elsevier, 1967)The behaviour of uranium in both organic and inorganic supporting electrolytes is examined, and also the influence of complexing agents on the incision in the curve, dE/dt =f(E). The addition of TEA to supporting electrolytes ...
-
(2009)The vibrational spectra of trans-p-coumaric acid (pCA) and syringic acid (SA) are discussed. The spectral fingerprints of the organic acids observed in the infrared and Raman spectra are assigned to fundamental vibrational ...
-
(2009)A detailed numerical study of several isomers of the Li10 cluster has been done. The analysis of the electronic localization function and the analysis of energy diagrams revealed the existence of one cluster with an inner ...
-
(2010)The present study shows the formation and characterization of the ionic-pair between the antibiotic oxytetracycline and the dye crystal violet in ammonia solution pH 9.0 ± 0.2 extracted into chloroform. The characterization ...
-
(2009)γδ T cells are a potent source of innate IL-17A and IFN-γ, and they acquire the capacity to produce these cytokines within the thymus. However, the precise stages and required signals that guide this differentiation are ...
-
(2009)The aim of the present study was to develop a classifier able to discriminate between healthy controls and dyspeptic patients by analysis of their electrogastrograms. Fifty-six electrogastrograms were analyzed, corresponding ...
-
(2009)Nucleation and propagation of a domain wall along a modulated wire as a function of its geometry has been investigated. In all the cases, nucleation began at the thicker section and propagated toward the thinner section, ...
-
(2009)The quality of lettuce (Lactuca sativa) seedlings is closely dependent on the substrate and the management practice during the transplant to the hydroponic system. This seed bed process may affect the normal development ...
-
(2009)We analyze the existence and stability of nonlinear modes localized at phase-slip waveguide channels and their intersections in two-dimensional photonic lattices with rectangular symmetry. While in linear lattices only one ...
-
(2009)A cyclotriphosphazene bearing two 4-oxypyridine groups on the same phosphorus atom, gem-[N3P3(O2C 12H8)2(OC5H4N-4) 2] (I), and its analogous polymer [[NP-(O2C 12H4)UNP(OC5H4NM)2) 0.3]n (II), have been used to prepare gold ...
-
(2009)We investigate theoretically the existence of bulk and surface discrete breathers in a one-dimensional magnetic metamaterial comprised of a periodic binary array of split-ring resonators; the two types of resonators used ...
-
(2009)The obligatory cost of living for endotherms is measured by basal metabolic rate (BMR), a variable that is known to change after thermal acclimation. However, the relative timing between variation in ambient temperature ...
-
Competitive interaction between introduced rainbow trout and native silverside in a Chilean stream (Springer Netherlands, 2009)The field experiment presented here elucidates the competitive effect of exotic trout on Chilean silverside. This is the first local experimental work that demonstrates the negative effect of trout on native fish from ...
-
Molecular mechanisms underlying glutamatergic dysfunction in schizophrenia: Therapeutic implications (2009)Early models for the etiology of schizophrenia focused on dopamine neurotransmission because of the powerful anti-psychotic action of dopamine antagonists. Nevertheless, recent evidence increasingly supports a primarily ...
-
(2009)Cuttings of five grapevine (Vitis vinifera) rootstocks were wounded and immediately inoculated with suspensions (approximately 5×10 3 conidia·mL -1) of either Phaeomoniella chlamydospora, Phaeoacremonium aleophilum or a ...
-
(2009)The Information and Communication Technologies (ICT) have brought several promises on participation and a closer relationship between authorities and citizens. In Chile, the Senate has developed two programs (Virtual Senator ...
-
(2009)Amyloids are a family of self-aggregating proteins implicated in various central nervous system disorders, including Alzheimer's disease (AD). It is thought that prefibrillar soluble forms of amyloid peptides, including ...
